FEED-VALVE FOR GASOliENE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 784,699, dated. March 14, 1905.

Appl cation filed May 13, 1904. Serial No. 207,816.

To (LZZ whm'lt it Nuty concern: 7

Be it known that we, CHRIs'rIAN PEDERsoN and OLE J OI-IN ANDRESEN, citizens of the United States, residing at North La Crosse, in the county of Lacrosse and State of isconsin, have invented certain new and useful Improvements in Feed -Valves for Gasolene- Engines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in atomizer-valves for gasolene-engines.

The object of the invention is to provide a valve for gasolene-engines whereby the speed of the engine may be controlled.

A further object is to provide a valve of this character whereby the oil will be thor, 2O oughly vaporized before entering the enginecylinder.

ith these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a view of a portion of a gasolene-engine, showing the application of the device. Fig. 2 isa vertical longitudinal sectional view through the valve-casing and valve. Fig. 3 is a horizontal sectional view of the valve-casing and valve removed from the engine. Fig. 4: is a vertical transverse sectional view of the same.

-Fig. 5 is a view of the valve removed from the casing, showing one side of the same. Fig. 6 is a similar view showing the other side, and Fig. 7 is a detail view of the wire-gauze cylinder adapted to be inserted into the valve.

Referring more particularly to the drawings, 1 denotes the engine,to which is attached a casting 2, on which is formed a valve-casing 3, the casting 2 being arranged between the carbureterand the side or. end of the engine and being in communication with the same. The casting 2 consists of a rectangular plate 4, provided near its upper and lower edges with bolt-holes whereby it is attached to the engine-casing over the inlet-opening of the same.

On the outer side of the plate a, and preferably cast integral with the same, is the valvecasing 3, which consists of a horizontally-disposed cylindrical tube closed'at one end, as shown. Projecting outwardly from the plate at is a gas-inlet 5, the walls 6 of which converge-outwardly and terminate in an internall y-th read ed socket? to receive a carbureter 8 of ordinary construction.

In the inner wallof the valve-casingformed by the plate 4 are arranged two series of obliquely-disposed dischargc-passages 9, those of one series projecting upwardly and those of the other downwardly above and below a cen tral line. These passages aiford communication between the valve-casing and the cylinder.

Within the casing 3 is arranged a tubular cylindrical feed-valve 10, having a stem 12, which projects outwardly through a cap 13, screwed into the open end of the casing and through a stuffing-box 1 1, arranged on the outer end of said cap. In one side of the tubular valve is arranged a series of inlet-apertures 15, and in the opposite side of the same are arranged a series of outlet-apertures 16, the latter apertures being considerably larger than the former, and consequently fewer in number. hen the valve 10 is in full open position, the apertures 16 in the same are adapted to register or coincide with the passages 9 in the inner wall of the valve-casing. and when the valve is turned one way or the other the apertures are thrown out of alinement, thereby restricting the openings between the valve-casing formed by the apertures 1 6 and passages 9, and by turning the valve to a sufficient degree communication between the valve-casing and cylinder may be entirely out off.

Within the tubular valve is disposed a wiregauze cylinder 17, one end of which is secured to a cap 18, which fits into the open end of the valve, as shown. In operation the vaporized oil from the carbureter passes into the valvecasing through the inlet or feed opening and is forced through the inlet-openings 15 in the outer side of the valve through the walls of the wire-gauze cylinder, then through the openings or apertures 16 in the inner side of the valve and the passages 9, formed in the inner walls of the valve-casing, and into the interior of the engine cylinder. In thus passing through the valve the oil is broken up into minute particles and injected into the cylinder of the engine in the form of a line spray. Said spray is directed into the cylinder in opposite directions by the oblique arrangement of the apertures 9, thereby evenly distributing the same into the cylinder.

On the outer end of the valve-stem is secured a handle 19, by which the valve may be turned to regulate the size of the feed-openings, as hereinbefore described, thereby admitting a greater or less charge of oil, which will cause the engine to run with a greater or less speed.

If desired, the valve may be automatically regulated by connecting the handle 19 with any suitable form of governor, (not shown,) thereby controlling the speed of the engine.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A feed-valve for gasolene-engines, consisting of a casing having an inlet-passage formed in one side thereof and discharge-passages formed in the opposite side of the same, a hollow valve arranged in said casing and having in one side small inlet-openings and in its opposite side larger outlet-openings which when said valve is operated coact with the discharge-openings in said casing. thereby regulating the feed of said engine, substantially as described.

2. A feed-valve for gasolene-engines, consisting of a casing having an inlet-passage formed in one side of the same, and oppositelydiverging discbarge-passages formed in its opposite side, a hollow valve arranged in said casing and having in one side inlet-apertures and in its opposite side outlet-apertures larger than the inlet-openings which when said valve is operated coact with the discharge-passages in said casing thereby regulating the size of the openings formed by said apertures and passages thus regulating the feed and speed of said engine, and means arranged in said hollow valve to break up or vaporize the oil pass ing through said valve, substantially as described.

3. A feed-valve for gasolene-engines consisting of a cylindrical valve-casing having an elongated inlet-passage formed in one side thereof, oppositely-.diverging discharge-passages formed in the opposite side of the same, a tubular cylindrical valve arranged in said casing and having small inlet-apertures formed in one side thereof and larger outlet-apertures formed in the opposite side of the same, said apertures being adapted to be thrown into and out of alinement with said passages by the turning of said valve, thereby regulating the feed of oil to said engine, and means arranged in said tubular valve, whereby said oil is broken up and vaporized before entering said engine, substantially as described.

4. A feed-valve for gasolene-engines consisting of a cylindrical valve-casing having an elongated inlet-passage formed in one side thereof, oppositely-diverging discharge-passages formed in the opposite side of the same, a tubular cylindrical valve arranged in said casing and having inlet-apertures formed in one side thereof and larger outlet-apertures formed in the opposite side of the same, said apertures being adapted to be thrown into and out of alinement with said passages by the turning of said valve, thereby regulating the feed of oil to said engine, and a cylindrical wire-gauze tube adapted to be inserted into said hollow valve, whereby the oil passing through the same will be broken up, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
